ios - Call ViewController method from App Delegate -

-

My view is in the controller, which opens a different view on the basis of a pin, it works when a button One end view, I can also put it in the viewdead mode, although I am using storyboards and the view of this method is firing on each view load from the loadload of the loadload loaded from the loadload of the system, so instead I was done with my app delilete. Function c To'm looking FinishLaunchingWithOptions it is basically redirected based on the presence of a stored PIN value on the app launch.

I've imported the View Controller in App Rep. #import "ViewController.h" FinishLaunchingWithOptions using the current code: 

  ViewController * RootViewController = (ViewController *) self.window.rootViewController; [RootviewConverter Inventview];   
 I do this but I am getting the error  
 Does not the visual interface selector announce 'interview' for 'visual controller'?  
 Here's my whole view controller.  
  #import & lt; UIKit / UIKit.h & gt; @ Interface view controller: UIViewController {IBOutlet UIT ext file * emailField; IBOutlet UITextField * passwordField; IBOutlet UITextField * Pinfield; IBOutlet UITextField * check pin; } @property (non-standard, strong) ibotlet UIWebView * webView; @property (strong, non-word) IBOutlet UIBarButtonItem * ShowEmailList; - (IBAction) showList: (id) this; - (IBAction) checkPin: (ID) this; - (IBAction) initView: (id) this; @end   
 and the method in my ViewController.m file:  
  - (IBAction) initView: (ID) sender {NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults ]; NSString * getPin = [Error Object foreaki: @ "pin"]; If ([getPin isEqualToString: @ ""]) {// do something} other {// do something else}}   
 How to correctlyify your initView method in my ViewController Any thoughts about doing .h file to fix this error? Thank you   
 
 
 You need to add an argument like this method:  
 < Code> [rootview controller init view: zero];

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
